为什么同样的js代码，内嵌可以执行，而复制建成文件外部调用就失败呢？

我把js代码直接复制新建个JS文件，html中通过id来读取，为什么不行，是还需要加什么吗？

Highcharts Example

    <style type="text/css">

#container {
min-width: 310px;
max-width: 800px;
height: 400px;
margin: 0 auto
}

    <script type="text/javascript">

Highcharts.chart('container', {

title: {
    text: 'Solar Employment Growth by Sector, 2010-2016'
},

subtitle: {
    text: 'Source: thesolarfoundation.com'
},

yAxis: {
    title: {
        text: 'Number of Employees'
    }
},
legend: {
    layout: 'vertical',
    align: 'right',
    verticalAlign: 'middle'
},

plotOptions: {
    series: {
        label: {
            connectorAllowed: false
        },
        pointStart: 2010
    }
},

                layout: 'horizontal',
                align: 'center',
                verticalAlign: 'bottom'
            }
        }
    }]
}

});

问题描述的都不太清楚截图也很混乱你可以把htm文件内容展示出来，把你写的外链的JS文件也发出来，这样才能看出来问题啊

可能是顺序加载，将外部js文件写在$(function(){ ... })内
